LTC7062IMSE#WTRPBF

Overview

The LTC7062IMSE#WTRPBF is a dual high-side N-channel MOSFET gate driver designed for automotive applications, certified to AEC-Q100 standards. It operates with an input voltage range of 3 V to 100 V and supports switching frequencies up to 500 kHz. The device features independent PWM inputs, adjustable dead-time control, and low propagation delay of 20 ns maximum. Output characteristics include peak currents of 2 A source and 4 A sink, with output voltages selectable at 80 mV or 150 mV above the supply rail. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Dual high-side gate driver architecture supporting independent PWM control for each channel
• AEC-Q100 qualified for robust automotive reliability and harsh environment operation
• Integrated adjustable dead-time control to prevent shoot-through in half-bridge configurations
• Low propagation delay ensures precise timing synchronization for high-frequency switching

Applications

• Automotive powertrain and chassis systems requiring high-voltage MOSFET control
• Industrial motor drives and inverters operating at elevated voltages
• High-side switching applications in automotive lighting and battery management systems

Procurement Notes

Verify the specific suffix WTRPBF indicates tape-and-reel packaging when ordering. Confirm AEC-Q100 certification requirements align with your automotive qualification standards. Ensure input voltage limits do not exceed 100 V during transient conditions. Check thermal dissipation capabilities for the MSOP package under continuous load. Validate compatibility with your system's logic levels for the PWM inputs.

Selection Notes

Select this component for applications requiring isolated high-side driving without external bootstrap capacitors. Consider the 100 V rating for systems exceeding standard 48 V architectures. Evaluate the 2 A/4 A output current capability against the total gate charge of the target MOSFETs. Compare propagation delay specifications if tight timing margins are critical. Verify that the adjustable dead-time range meets the switching frequency requirements of the design.

Part Context

This part belongs to the LTC7062 family of high-voltage gate drivers from Analog Devices. It complements other series members like the LTC7062EMSE by offering automotive-grade qualification and specific packaging options. The device addresses the need for reliable high-side switching in modern electric and hybrid vehicles where voltage levels and environmental stresses are significant.

Replacement Considerations

Direct substitutes may include the LTC7062EMSE#PBF for non-automotive versions or the LTC7062IMSE#TRPBF for different reel quantities. Verify pinout compatibility and electrical parameters before substitution. Cross-reference with other Analog Devices high-side drivers such as the LTC7065 for similar functionality.
